' ltu'rnnnronn and CHA NonY; IowNsnNn,

citizens of the .United States, and residents of Jerome, county of Yavapai,.;Stateof Arizona, have inventeda new and useful Smokeless -He'ater, of which ,the l following is a specification. v

The present invention relates tolmprove ments in heaters and is principally intended;

proper function of the leaves as thebreathingorgans of the trees. It is proposed in the present invention to provide means for heating an orchard tially smokeless. 7

With this object in view we have shown the preferred form of our invention in the accompanying drawing in which:

Figure 1 represents a front elevation of our heater and Figure 2 represents a vertical section through the same. lVhile only one form of the invent-ion is shown in the drawings and described in the specification, we wlsh to modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

Our heater 1 comprises a preferably cylindrical housing 2 covered by the plate 3, the flange 4 of whichengages the upper marginal part of the housing. In the lower portion of the housing a grate 6 rests on an annular angle iron 7 secured to the wall of the housing by any suitable means as by the rivets 8. The housing is divided into two parts by means of a; conical plate 9 having a. central opening 11 and being provided with an upturned flange 12 adapted" to engage and tobe securedfto the wall of the housing. The portion 13 underneath this conical plate constitutes the firebox and the portion 14 above the plate'forms the smoke chamber.

To the outside of the housing is secured Orchard heat- 7 that will be substanhave it understood'that various changes or ne -s eam, Y

Pipes 23-are' supported inth'e cover plate 3 and extend downwardly'towithin a few inches of the: conical plate 9 and upwardly to; any desired height f fire box through a lower door 26. 3

The fire on the grate heats the conical plate 9 and'the smoke from the fire-is discharged into the smoke chamber 1 1.. Simultaneously, water is admitted through the pipe 21 from the reservoir 17 and drops'on the conical plate 9 where it is converted immediately into steam; The latter absorbsthe c r V 651 7 .A door Ztis provided at a suitableheight for the fire box and air isadmitted to the' The operation of thedevice is as follows l V smokein the smokechamber and the prodnot is carried off through the pipes 23 to heat the surroundingair sufliciently to prevent the frostfrom damaging the trees or the fruit on the same;
